Abstract
The present invention relates to an apparatus for determining the hot tearing susceptibility of metallic melts, comprising a casting mould, which has a first subvolume and a second subvolume, the second subvolume being formed as a tubular portion with a first end and a second end, the first end being connected to the first subvolume, comprising a measuring element, which extends into the second end of the tubular portion, and comprising a measuring device for recording a force on the measuring element and/or a change in position of the measuring element in the direction of extent of the tubular portion, the measuring device being coupled with the measuring element. The object of allowing an improved quantitative and qualitative determination of hot tearing susceptibility is achieved by the cross-sectional area of the tubular portion being reduced in the direction of the second end in each and every subportion of the tubular portion that may be selected substantially over the entire length.
